EV tariff terms and conditions

Updated on 16th June 2025

In addition to Sainsburys Energy standard residential terms and conditions the following terms will apply. In the event of any inconsistency between these terms and the standard terms and conditions, these terms shall prevail.

1. About your tariff

1.1 Tariff duration: This tariff is a fixed price tariff for 12 months and it offers electricity at a lower price during a daily defined ‘off peak’ period of 7 hours, and a higher standard rate at all other hours of the day.

1.2 Confirmation of your actual prices and off peak times will be sent to you by email.

1.3 No exit fees will apply if you decide to switch to another tariff or supplier within the 12 month period.

1.4 Charges: You shall be liable for the daily standing charge and unit rates for each fuel under this tariff. Additionally, Valued Added tax (VAT) shall be applied. 1.5 The prices stipulated in your contract shall remain unchanged except under the following circumstances:

1.6 You elect to change your tariff

1.7 Governmental or regulatory bodies mandate changes necessitating price adjustments, such as modifications in the applicable VAT rate. In the event of such changes, we shall provide you with a notice of any resulting price adjustments

1.8 Due to the way this tariff works, your In-Home Display will stop working.

1.9 Sainsburys EV tariff is a new and evolving beta product. Our communications and your online account may look and behave a little differently to normal as we continue to optimise the product.

2. Charges and payment

2.1 We will work out your electricity charges by multiplying the relevant unit rate with how many Kilowatt hours (‘kwh’) you use during the off-peak and standard periods, using the half-hourly readings we get from your smart meter.

2.2 We will bill you on a monthly basis. Your bill will consist of the consumption charges calculated on the basis of your meter readings and the peak and standard unit rates, daily Standing Charge, and VAT at 5%.

2.3 If, for any reason, a technical fault has occurred, or your meter stops communicating and we are unable to obtain your usage, we will take your average consumption for peak and standard periods to estimate your bill(s) until the technical fault is corrected or your meter is communicating again. If we do not have sufficient consumption data, we will use average consumption figures provided by Ofgem.

2.4 In the event we are unable to start communicating with your meter again, we will contact you to discuss the options available. If we are unable to contact you, we will move you to our Standard Variable tariff (Sainsburys Standard Variable) and let you know. You will then be able to choose another tariff of your choice. 

3. Eligibility 

3.1 To be eligible for this tariff you must: 

3.2 Own or lease an electric or hybrid vehicle, or have a solar storage system. 

3.3 Have a smart meter that can send meter reads automatically. 

3.4 Consent for us to obtain consumption data from your smart meter at 30 minute intervals. We will use this data to bill you, so you can view your energy consumption on your online account, and for settlement of our purchasing on the electricity markets. 

3.5 You must pay for your energy by monthly Direct Debit, and manage your account online. 

3.6 If you withdraw consent for us to read your electricity consumption through your smart meter every 30 minutes, the tariff will end, and you will move to our Standard Variable Tariff (SVT), Sainsburys Standard Variable. 

3.7 If you stop paying by Direct Debit and/or manage your account online, we reserve the right to end the Sainsbury’s EV Tariff and switch you to our Standard Variable tariff, or another tariff of your choice for which Direct Debit and online account management are not a requirement. 

3.8 You can keep this tariff if you move house and still meet the eligibility criteria. 

4. Testing your smart meter 

4.1 If you are already a Sainsburys Energy Customer, we must run test-reads of your smart meter. 

4.2 for up to 5 days and you will remain on your existing tariff during this period. 

4.3 If the tests are successful, your tariff begins when the tests have completed. 

4.4 If the tests are unsuccessful, you will remain on your current tariff. 

4.5 We reserve the right to withdraw this tariff at any point.
